Abstract: 1,239,579. Reinforced thermoplastic sheet materials. R. J. COX. 12 Dec., 1969 [25 Sept., 1968], No. 45552/68. Heading B5N. Synthetic thermoplastic polymeric sheets are reinforced with single plastic coated wires which are individually heated by passing through each wire an electric current, the heat so generated in the wire raising the plastic coating on the wire to a temperature sufficient to form a local molten surface on the thermoplastic sheet when the wire and thermoplastic sheet are pressed together, the structure being allowed to cool after pressing together the heated wires and thermoplastic sheet. The wire may be tensioned during heating and cooling to prevent distortion. The wire may be a metal rod, tube or wire which may have an anti-corrosion coating under the plastic coating, e.g. galvanized iron wire, and may be a composite wire built up of strands of wire twisted together. Pressure may be applied in a press, the platen which applies pressure on the side of the thermoplastic sheet preferably containing a groove into which the reinforcing wire having a plastic coating is located when the sheet and wire are pressed between the platens. Pressure may be applied in a calendering process. The plastic coating on the wire may be the same as the thermoplastic polymeric sheet, e.g. polyethylene or polypropylene, or may be any plastic material compatible with the thermoplastic sheet so that bonding will take place. The plastic coating on the wire may contain a bonding assisting material. The wire may be coated by passing the heated wire through a powdered thermoplastic material which may be suspended in a turbulent gas or by sliding the plastic material in tubular form over the wire. The wires may be bonded across the breadth of the thermoplastic sheet parallel to each other and may be greater in length than the breadth of the thermoplastic sheet. Alternatively the wires may be bonded diagonally across the breadth of the sheet in zig-zag configuration, the wire ends extending beyond the edges of the sheet being linked together. Two or more thermoplastic sheets may be bonded together with the wires and heat sealed along the edges between the wires, the sheets being separated over the area between the wires by an air or other gas filling.

In the production of rod-like tobacco articles, the articles are rolled to attach wrappers thereto and their wrappers perforated during the course of the rolling movement. The process may be carried out in an apparatus comprising two rolling surfaces relatively movable one to another and spaced apart by a distance equal to or less than the diameter of the rod-like articles, at least one of these surfaces being provided with raised portions to perforate the wrappers during rolling. A suitable apparatus is shown in Fig. 1 wherein rod-like articles, positioned in the grooves 4 of rolling drum 1 are conveyed to the rolling gap between the movable rolling surface 3 and stationary rolling surface 7. The rod-like articles are rotated about their axis during passage under the surface 7. The needle projections, 22 and 23, which are positioned on surface 7 and are arranged in a circular pattern (Fig. 2, not shown) pierce the wrappers of the rod-like articles during the rotation of phase articles under the surface 7. In an alternative embodiment (Figs. 3 and 4, not shown) the rod-like articles are carried in grooves on a drum, which drum has mounted on its rolling surface, needle projections. The rod-like articles contact a rolling band which is moving at a slower speed than the rotation of the drum, thus causing the rod-like articles to roll, the needle projections piercing the wrappers of these articles.

[Also in Division G3] A metal casting apparatus comprises a mould 2, a metal supply means 40 above the mould 2, a gas-sealed chamber (1) below the supply means and above the mould 2, the bottom of the cavity being defined in use by the top of the molten metal in the mould 2. Gas is supplied to the cavity through a control valve 6, its pressure sensed at 10, and a signal derived from the measured pressure sent to a control block 13. The amount of molten metal in the supply means 40 is sensed at 56, a signal derived from the measured pressure sent to control block 60 and from there to block 13 where it is combined with the gas pressure signal. The combined signals are then used to control the gas flow valve 6. Optionally, a pressure release valve 62 is provided to vent the chamber (1) when the pressure therein exceeds a predetermined value.  In a continuous casting apparatus the mould 2 reciprocates and is mounted on a flexible diaphragm 45. Gas from a source 3 passes through a pressure reduction valve 4 and is stored in a reservoir 5 for supply to the chamber (1) through the flow valve 6 and a further reservoir 7. The reservoir 7 functions to dampen the gas pressure oscillations caused by the oscillating mould 2. The pressure in the chamber (1) is sensed by a flexible diaphragm 52 which moves the core 54 of a solenoid to induce a signal which is sent to control block 13. The amplified and modified signal is sent to one winding of a double oppositely wound coil 17 in the flow valve 6. To the other winding is applied a voltage corresponding to the pressure desired in the chamber (1). The coil 17 operates an hydraulic amplifier which controls the opening of the gas pressure regulating valve 34-38. The above-mentioned signal is modified in a control block 23 by a signal from weight sensors 56 dependent on the amount of metal present in the supply means 40. Gas pressure and metal weight signals are also sent to control block 63 which operates a chamber venting valve 62 when a preset ratio between the signals is exceeded.
